861-acre lake near Grant County. The lake tops out around 65 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Blue Lake runs 861 acres with 5.6 miles of edge. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 25% of this chart. The basin spans about 2.6 mi end to end and 0.9 mi across at its widest. You'll find it in Grant County. For a second option, Park Lake lies 2 mi northeast.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Spring rainbow trout concentrate at Main-lake point, a good-rated point around 1 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow feeding flat (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 15 to 35 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Dock / pier line (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | open water | Blade bait, Jigging spoon |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 20 to 45 ft. Top water on the chart: Main-lake point, a point in the 1 ft range, good in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (1 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (1 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | open water | Blade bait, Hair jig |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (16 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Dock / pier line (9 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow feeding flat (16 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Shallow feeding flat (16 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: crappie sit in 2 to 8 ft that time of year. Warm water sends them out to 10 to 25 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Dock / pier line, a dock line in the 4 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Dock / pier line (4 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shallow feeding flat (16 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Dock / pier line (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | open water | Tungsten jig + soft plastic, Tiny jigging spoon |
